Gdańsk AI is a full stack AI voice chatbot (speech-to-text, LLM, text-to-speech) with integrations to Auth0, OpenAI, Google Cloud API and Stripe – Web App, API and AI
Web API
It uses Stripe to provide payments infrastructure, so users can buy bibs – the API tokens. Auth0 is used to provide authentication and authorization. You can use them for free – Auth0 has a free tier up to 7000 users per month. Stripe only charges fees from purchases, so you have no ongoing costs from any of them.
If you want to use these services, you have to set up your Stripe and Auth0 accounts and put API keys into .env in web-api/ directory.
